Online Now: Nitric oxide drives proteomic diversity through alternative splicing Online now:
Schindler et al. report that RNA-binding proteins undergo widespread S-nitrosylation at evolutionarily conserved sites. S-nitrosylation of the master splicing regulator PTBP1 alters RNA-binding properties to reprogram the transcriptome and proteome. Nitric oxide thereby coordinates gene and protein regulation in cellular physiology and disease.
